Diamond Boost Slot Review
Diamond Boost is a 3×3 AGS slot with 9 fixed paylines, multiple RTP configurations, and a signature Diamond Boost Bonus that can repeatedly upgrade non-jackpot payouts. Wild multipliers and fixed jackpots add extra punch to this classic 7s-and-diamonds style.
Diamond Boost keeps the math easy to follow—short reels, clean paylines, and one main feature that “levels up” payouts when Diamond Boost symbols appear. With RTP and bet limits varying by operator, the demo is the best way to confirm your exact version.

What kind of slot is Diamond Boost?
Diamond Boost is built like a modern classic: a compact 3×3 grid, nine fixed paylines, and a simple symbol set (7s, BARs, and diamonds).
It doesn’t rely on long bonus rounds—most of the excitement comes from a repeating “boost” mechanic that upgrades payouts.
How Diamond Boost works
- Pick your stake and spin on the 3×3 grid with 9 paylines.
- Land line wins on classic symbols (7s and BARs) from left to right.
- Watch for Diamond Boost symbols that trigger the boost sequence and can improve non-jackpot payouts.
- Look for jackpot combinations on an active payline for fixed jackpot awards.
Main features
- Diamond Boost Bonus that can increase non-jackpot paytable values and award an extra spin.
- Boost stacking — each Diamond Boost symbol can upgrade values again (up to 8 boosts total, version rules apply).
- Wild multipliers — special symbols can act as wilds for 7/BAR wins and multiply payouts in the right combos.
- Fixed jackpots tied to specific 3-of-a-kind combinations on active paylines.
- Classic readability — short reels, fixed lines, and quick outcomes.
Diamond Boost Bonus explained
The headline mechanic is straightforward: when a Diamond Boost symbol appears, it starts a bonus flow where non-jackpot paytable values step up.
Each Diamond Boost symbol upgrades the values again and awards a single extra spin, letting the “boost level” climb if you keep landing diamonds.
The bonus ends when a spin shows no Diamond Boost symbol, and the game caps the number of boost steps (commonly up to 8).
In practice, this creates a nice rhythm: lots of normal spins, then occasional “heater” moments where payouts improve for a short burst.
Jackpots and multiplier wilds
Diamond Boost uses a tiered fixed jackpot idea: certain 3-symbol combinations on an active payline award jackpot prizes.
Outside jackpot outcomes, special symbols can also work as wilds for 7/BAR wins—and can multiply those wins when they land in a paying line.
Even with a steadier volatility profile, jackpots and boosted streaks can make results feel uneven. If you’re playing a high max-bet configuration, set a session budget and stop-loss first. For safer play tools, see Responsible Gambling.
Bonus structure and payout profile
Diamond Boost is less about rare mega-bonuses and more about repeatable value: line hits in the base game plus periodic boost streaks that lift non-jackpot symbol payouts.
That’s why it often feels “steady with pops” rather than long droughts followed by one huge feature.
If you’re choosing between RTP versions, the difference is meaningful over time. When possible, select the higher RTP configuration (and confirm it inside the game).
Who will enjoy Diamond Boost?
- Players who like classic 7s/BARs slots with a modern twist.
- Anyone who prefers fixed paylines and easy-to-track wins.
- Fans of short, repeatable features instead of long bonus modes.
- People who enjoy jackpot tiers without complicated rules.
